Material Characteristics of Prestressed Concrete 7 Tensile strength of prestressing steel strands is normally 270 ksi. Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces. Prestressing tendons should be clean and free of harmful matter such as loose mill scale, loose rust, mud, oil grease, or any other coating which could reduce the bond between the concrete and the steel.
